Hello Autocar Team, I am from Pune, and my father owns a 2021 Kia Sonet HTX 1.0 iMT. Our annual running is between 5,500 and 6,000 km, and most of our usage is in the city. Due to concerns about E20 compatibility and a significant drop in fuel efficiency, he is considering selling the Sonet and buying a Maruti Suzuki Baleno AGS (Zeta or Alpha). He also wants the convenience of an automatic transmission. His budget is Rs. 10 lakh on-road. Considering our usage pattern and fuel efficiency concerns, would buying the Baleno be a practical decision, or should he continue with the Sonet?
If your 2021 Kia Sonet 1.0 iMT is serving you well without any issues, we'd suggest you retain it. On the E20 issue, ethanol blends can reduce fuel economy slightly, but the drop is not likely to be significant enough to justify selling a good car. Keep in mind that you will lose a fair chunk of money as far as residual value goes, which won't justify the additional outlay your next new car will command.
The bigger question is whether the Baleno AGS is the right upgrade. At under Rs 10 lakh on-road, you are looking at the Zeta AGS, which is a well-equipped car. This Maruti Suzuki car is comfortable, reliable and very easy to drive in the city. The AGS gearbox is an automated manual, which will be more convenient than the iMT. And the Baleno's 1.2 NA petrol will certainly be more efficient than the Sonet's 1.0 Turbo. That said, as far as quality and performance go, the Baleno will feel like a step backwards compared to your outgoing Sonet.
If your father is looking for a smoother city driving experience and better fuel efficiency, the Baleno AGS is a good choice. If the Sonet is otherwise running well, there is no urgent need to sell it purely because of E20 concerns.
